Be it .known that l, Enxas'r BRISCOE Mama, a citizen of the UnitedStates, and a resident of Augusta, in the "county of Richmond and Stateof Georgia, have invented a new and- Improved Excavating and(onveyingSystem, of which the following is a full, clear, andexactdescription.

My invention relates to systems for excz vating, various materials andtransportingthem to desiredpoints in suitable recepta =cles.- Itsprincipal object is to provide a simple and efficient system which willmeet a wide range of requirements and be usable in many situations.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts mall the views.

Fig. 3 is a transverse section on the line 3 3 ofFig. 2 and more particularly illustrating the excavating apparatus. Fig.4 shows one of the power-nutltiplying mechanisms in top plan. Fig. 5 aside elevation thereof. Fig. (i is a side elevation of one of the'cars.Fig. 7 is an end elevation of said car, showing it in place upon therails. of the gripping device. Fig. 9 is a top plan view of theoperating mechanism for the excavator. Fig. 10 is an end elevationthereof looking from the right in Fig. 9. Fig 1-1 a sectional detail onthe line 11- 11 of Fig. 9. Fig. 12 is a-simila'rview on the line .12 12of Fig. 9. Fig. 13 is adetail view showing the construction and.organization of certain parts more clearly; andFig. l4 a plan view of ascoop and a portion. of the cable, showing the chain sections thereofand in engagement with theprojections of the scoop.

. l0 designates a mill or structure to which the material is to beconveyed and to which 'leadtracks 11' 11, which may extend in anydesired direction and are preferably connected withinthe structure by aswitch 12. Between the tracks throughout their length are rolls 13,which support and guide an endless cable 14. WVithin the structure thiscable engages a power applying and multiplying mechanism A, this havingsheaves 15 and 16, fixed upon shafts 1217, ournaled in a frame '18 Inthe sheaves are a suitable number of Fig. 2 is a- Fig. 8 is a detail intop plan viewalined grooves toreceive the cable, the cable ZiII'Stpassing under the sheaves at a into the outermost grooves thereof,thence up. over the sheave 15 and around the sheave16,*and.

ling the application of power. At the opp'oe sitel end of the system thecable engages atake-up'deflcc comprising a sheave 24, over which itpasses, said sheave being mounted upona car 25, having wheels runningupon the inner rails of the tracks. To the journal of the sheave isconnected :1 cable 26, secured at its opposite extremity to a relativelyfixed drum 2,7, associated with which is a ratchet-lever 255, by meansof which the drum may be turned to-move the car, and,

thus place the proper tension upon the cable. Situated between the milland the take-up device is a IlfzlIlSfGl'IiIlg-flfilll 29,mounteduponsets of wheels 30, cooperating with both tracks, a portion ofthese wheelsbeing joiurnaled. upon extensions 31 31. The' fr'amepreferably has laterally-projeeting heal-us or members 32, from whichbraces 33.111 tend to the upper portion of the frame. etween the outerends of the beamsandrelatively fixed blocks or members 34 wedges 35 maybe driven, tendin to fix the position of the frame wheels.

Carried byone of the frame extensions isa multiplying mechanism B, whichmaybe in all respects similar to that designated as A and previouslydescribed, except that here. the cable passes from the sheaves inopposite;

lirections along the track. The shaft 21- of this mechanism B may beprovided with a driving-pulley 35 to, which power ma' vbe applied, iffor any reason it is more convcnlent to operate the system from thispoint; rather than at the mill. The shaft also 1mg;

This grip mechanism may alsobe operated:

in any customary m'a'nner'to release it from the cable to stop the car.Beneath the'points of -discharge of the'scoops is a vtrack 74, mountedupon a platform 75, having at-its or Ways 77-, situated at thelower-portion of j the transferring-frame.

This ,dra- Ws thescoop over the surface from wh ch the ma: terial is'to be taken-and upona proper 'ma- 'nipulation of the handle'is loaded as 'it advances. Thishavingbeen accomplished, the lever 45 is moved to release the clutch andinto cooperation with the friction-roll upon the shaft 41'. Thiscontinues the travel of the scooptoWard the transferring-frame, but 7,

.viously delivered its charge isfmoved out-" wardly and carried to apoint adjacent .to the guide-rolls 62. The operation of the clutchlever46 and an opposite movement of the lever 57 rotate the drum in thesamemanner, but in the opposite direction,- causing a reverse movement ofthe cable and the de-' livery of a load by the companion scoop, theframe-platform having been movedto bring the carinto the properposition. When the loading of the car is completed, it is started downthe incline to the track along which the cable 14 moving toward themill, and its I gripping. device engaging the cable causes'it intoengagement with this run of the cable,-

to be moved into the mill. Here it is emptied and transferred by, theswitch to the.

out track, its gripping mechanism brought the drum. \Vith the sectionssecured to one another this would obviously be impossible, sincerotation in either direction would pay off one run as rapidly as theother was wound on. It will be obvious that by a slight rearrangement ofthe elements upon the frame the excavating-cable may be caused tooperate at either side of the-tracks.

Having thus described my invention, I
